In unix, SQLite has to use global variables to work around the well-known design bugs in posix advisory locks. And so if you have two different instances of SQLite running on unix, they will use different global variables, causing them to break each others locks and you will get database corruption. But as far as I know, that is not a problem on Windows. On the other hand, this is not something that we have ever tested. -- D. Richard Hipp drh at sqlite.org
